Heights of offspring of Zea mays

Description

A dataset containing the height of 15 pairs of the offspring of maize plants.

Usage

cornheight

Format

A data frame with 15 pairs of observations and three variables:

Pair

Pair number, a numeric vector

Cross

Height of cross-fertilized plants, a numeric vector

Self

Height of self-fertilized plants, a numeric vector

Details

Darwin took 15 pairs of Zea Mays plants, where within each pair the two plants were of exactly the same age, were subjected from the first to last to the same conditions, and were descended from the same parents. One individual in each pair was cross-fertilized and the other was self-fertilized. The heights of offspring were then measured to the nearest eighth of an inch. This data set was used by Fisher (1935) to introduce the idea of the randomization test with paired comparison data.
